ABSTRACT:
The opposite ends of a conveyor tunnel furnace are free of physical seals and instead each end is provided with a gas seal tunnel. Each gas seal tunnel is formed by at least two spaced apart, transversely extending fluid flow restriction members defining at least one gas seal chamber therebetween. Gas is supplied in a fixed volumetric flow to each gas seal chamber and maintained at a pressure greater than that of the furnace or of the ambient atmosphere. The flow restriction members are adjustable to cause accelerated gas flow therethrough, or therearound, to prevent mixing or diffusion of gases.
